Board your pontoon easily and safely with the Extreme Max Undermount Pontoon Ladder. This welded aluminum ladder attaches to two pontoon stringers and stows under the front deck. Ladder is secured in the stowed position by a heavy-duty rubber strap. Deploy the ladder by unhooking the strap and sliding the ladder out and into the water. Wide, sturdy traction rungs make boarding comfortable for children or adults with 12" rung spacing. Boarding ladder area: 12.5" wide with 1.5" grooved rungs. Includes stainless steel mounting hardware. Note: For pontoons with underside sheeting or closed channels that do not allow access to the topside of the pontoon's stringers, additional mounting hardware will be needed and is not included. Use marine-grade stainless steel self-tapping screws to fasten your ladder in place instead of the provided mounting hardware.
